I changed smartphone from Xiaomi 10 Lite 5G to Xiaomi 11T: same group and same Android 11. I upgrade my 945 from 9 to 9.6 in the same time. Now I have link (I can download activity and I can see every notify like call, SMS and other), but with every widget that need link (like Minutecast or weather conditions) I have message that tell me there is no link. Very strange, because I have link and I have turn off every energy save turn off of Garmin Connect and IQ Garmin (that function regular). I can not use DEM for calibration too.
